摘　　要：用红外光谱表征了水不溶性羧基淀粉接枝聚合物(简称ISC)结构。用静态法和动态法研究了ISC去除电镀废水中Cr3+和Cd2+的效果及pH值对去除效果的影响,并对其吸附机理进行了探讨。Water-insoluble carboxyl-containing starch graft polymer (ISC) was prepared by crosslinking with epichlorohydrin, then grafting with acrylonitrile, followed by base saponification to convert nitrile group into a mixture of carboxamide and carboxylate groups. Fe2+-H2O2 was used as iniator for graft polymerizaton. Infrared spectra of ISC was determined. The experiment of influence of pH, static and dynamic tests on the removal of Cr3+and Cd2+ from electroplating wastewater with ISCwere done. The adsorptive mechanism was also discussed.
